2010-11-19xen: add extra pages to balloonJeremy Fitzhardinge2-4/+18
Add extra pages in the pseudo-physical address space to the balloon so we can extend into them later. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2010-11-16xen/events: use locked set|clear_bit() for cpu_evtchn_maskJeremy Fitzhardinge1-2/+2
The per-cpu event channel masks can be updated unlocked from multiple CPUs, so use the locked variant. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2010-11-16xen/evtchn: clear secondary CPUs' cpu_evtchn_mask[] after restoreJan Beulich1-2/+5
To bind all event channels to CPU#0, it is not sufficient to set all of its cpu_evtchn_mask[] bits; all other CPUs also need to get their bits cleared. Otherwise, evtchn_do_upcall() will start handling interrupts on CPUs they're not intended to run on, which can be particularly bad for per-CPU ones.

2010-11-12xen: implement XENMEM_machphys_mappingIan Campbell7-18/+47
This hypercall allows Xen to specify a non-default location for the machine to physical mapping. This capability is used when running a 32 bit domain 0 on a 64 bit hypervisor to shrink the hypervisor hole to exactly the size required.

2010-11-10xen: do not release any memory under 1M in domain 0Ian Campbell1-7/+11
We already deliberately setup a 1-1 P2M for the region up to 1M in order to allow code which assumes this region is already mapped to work without having to convert everything to ioremap. Domain 0 should not return any apparently unused memory regions (reserved or otherwise) in this region to Xen since the e820 may not accurately reflect what the BIOS has stashed in this region.

2010-11-10xen: events: do not unmask event channels on resumeIan Campbell1-7/+18
The IRQ core code will take care of disabling and reenabling interrupts over suspend resume automatically, therefore we do not need to do this in the Xen event channel code. The only exception is those event channels marked IRQF_NO_SUSPEND which the IRQ core ignores. We must unmask these ourselves, taking care to obey the current IRQ_DISABLED status. Failure check for IRQ_DISABLED leads to enabling polled only event channels, such as that associated with the pv spinlocks, which must never be enabled: [ 21.970432] ------------[ cut here ]------------ [ 21.970432] kernel BUG at arch/x86/xen/spinlock.c:343!

2010-10-28watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init codePrarit Bhargava1-2/+0
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove to fail because of an incorrect usage count. The probe for this driver does a for_each_pci_dev() which gets a reference for a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop puts a reference for a pci_dev when iTCO_wdt_init() fails, so the iTCO_wdt_init() does not need to do any pci_dev_put()'s. The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2010-10-29mfd: Fix TWL4030 COR bit polarity for BCI SIH blockGrazvydas Ignotas1-1/+2
The chip TRM documentation contradicts itself about this bit, page 174 of swcu050e says bit should be 0 for clear-on-read behavior, while page 487 says it should be 1. Testing shows it should be 1, so set the .set_cor flag accordingly. This is needed for upcoming BCI charging driver to function.

2010-10-29mfd: Add devices platform data when the cell data size is not 0Brian Harring1-4/+6
When the cell data_size is 0, the resulting platform_data pointer will be set to ZERO_SIZE_PTR. That could be misleading for device drivers running a NULL check on thei platform_data pointer before dereferencing it.

2010-10-29rtc: Add support for the rtc found in the MC13892 PMICUwe Kleine-König4-433/+443
The mfd driver for MC13783 recently got support for MC13892 and was renamed accordingly from mc13783-core to mc13xxx-core. Do the same for rtc-mc13783. The only relevant change is to use platform id's to tell the platform bus that this driver is responsible for mc13892-rtc devices, too.

2010-10-29mfd: Adding twl6030 mmc card detect support for MMC1kishore kadiyala4-3/+112
Adding card detect callback function and card detect configuration function for MMC1 Controller on OMAP4. Card detect configuration function does initial configuration of the MMC Control & PullUp-PullDown registers of Phoenix. For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect, the suspend/resume initialization which was done in omap_hsmmc_gpio_init previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

2010-10-29mfd: Add mc13892 support to mc13xxxUwe Kleine-König6-882/+1113
mc13892 is the companion PMIC for Freescale's i.MX51. It's similar enough to mc13782 to support it in a single driver. This patch introduces enough compatibility cruft to keep all users of the superseded mc13783 driver unchanged.

2010-10-29mfd: Remove obsolete mc13783 private dataUwe Kleine-König1-18/+9
The regulator driver was converted to get the needed data directly from platform_data by a10099b (regulator/mc13783: various cleanups) so regulators and num_regulators can go away. Then apart from the flag indicating that the adc does a conversion, flags is only a copy of the flags member of platform_data. This flag isn't needed to be returned by mc13783_get_flags, so mc13783_get_flags now gets the flags from platform_data, too and the driver private member is renamed for clearity.
